PIP-4048MS inverter

Update on AVR (Arduino hardware) to PIP I have an Arduino M2560 board working as an interface between a PC with terminal and the PIP Type a command into the terminal press enter and the AVR calculates the CRC adds it to the command and then sends it to the PIP. The PIP sends its response to the AVR ...

PIP-4048MS inverter

But then, with a 2 pole device, you can get a 125 Vdc rating (63 Vdc per pole) from an ordinary non-polarised 250 Vac Hager, Merlin-Gerin or ABB 2-pole breaker. /[/URL] The new Hager breakers are no longer DC rated (I have spoken to Hager) even for 48v telecoms where they were used for decades.

PIP-4048MS inverter

20 years ...over 70000 cycles at 20% DOD from a AGM battery I would like to see that! As I said depending on the type of battery large (1000Ah) 2volt flooded cells with pure lead lead plates can last 20years or even more. I got 13years out of my last lot of VRLA batteries but note those 100Ah 12v b...

PIP-4048MS inverter

Northland your question about cycle life of AGM The life of your batteries will depend on the depth of discharge if you only use 20% of the available storage you can get 10 to 20 years depending on the type of battery. Now you have 400ah so using only 80ah worth of power (about 4Kwh) is a good targe...

PIP-4048MS inverter

Now as far as the number of panels in series. On one system I started with two in series x 6 sets 12 panels ran that for 12 months. It worked ok and I was able to get the maximum power from the panels. I have now changed it to three in series x 4 sets still the same 12 panels and it works giving a l...

Hello Northland I have my PIP-4048s (2 sets of them 200Km apart) hooked up to TCPIP it can be wireless or cabled Requires no modifications to the unit I do use the power from the PIP on the RJ45 to run the wireless unit with a small switch mode regulator module this is the same power that runs the r...

PIP-4048MS inverter

With mains off (plug out of power point) , switch on the bottom off and batteries connected the unit is communicating so the cpu is up and running I also have the back light on with the panel so a bit more there.
The unit says its in standby mode this is the old style with heat sink on top.

PIP-4048MS inverter

250ma is what I see with no solar, no mains and the switch on the bottom off but note the fans are running at very low speed so this may be a third of the power.
The batteries are only 4 x 12v 7ah and old so I need to leave the mains on.

Yes it will charge the battery when the sun comes up.

Re: PIP inverter repairs and hardware modifications

Is it under warranty?
If it is why void the warranty.
I have units here working 24/7 for over 12 months have had no problems with the caps and as they are still under warranty (2 years on my ones) I will wait till that ends.
I have lead acid batteries connected to the units.

Re: PIP inverter repairs and hardware modifications

It is good to have real data. Today with temps here at 27deg I had the air con running and then boiled the kettle this had the unit at 3200watts for about 4 mins . As the top of the inverter heat sink had gone past 42deg the two 125mm fans mounted on the sides at the top were running (my add on exte...

Re: PIP inverter repairs and hardware modifications

Coulomb have you turned the fans around it would be good to see the difference if any ?
Also if you get a flexible driver you can remove fans without taking the units apart

Those CR225 batteries are the crown type of the Trojan T105s they are 225Ah most people seem to think the American made Trojan are the best ones I will find out over time with my 8 T105s but people I have spoken to who have off grid systems and Trojan T105s have had them for 10years or more.

baal The battery that gives you the most for money spent are the Trojan T105s and a watering kit to make filling with water easy. Now if you look around every now and then good second hand AGM/VRLAs do come up cheap just have to do the research to find their age and history. As an example http://www...

PIP-4048MS inverter

As a quick fix maybe http://www.lowenergydevelopments.com.au ... -Regulator
Check with them that it does not go above 60volts when it charging
After looking at the instruction sheet it seems you can set the max charge voltage so this unit should work OK

I now have a temperature probe in the fins of the 230v inverter it gets to 48c with a light load of 300watts I think they may have gone too far with the fan slow down.

Re: PIP inverter repairs and hardware modifications

I have a question for those that have taken their units apart and looked closely at the circuit and components as I still have warranty I have not completely pulled my ones appart. Other than the 63V capacitors is there any reason it could not go to 62volts ? I know its firmware will not but what ab...
